97. Check and, if necessary, correct the tire air
pressure, and then block up the ATV so that
all of its wheels are off the ground. Alterna-
tively, turn the wheels a little every month in
order to prevent the tires from becoming de-
graded in one spot.
8. Cover the muffler outlet with a plastic bag to prevent moisture from entering it.
9. Remove the battery and fully charge it. Store it in a cool, dry place and charge it once a
month. Do not store the battery in an exces-
sively cold or warm place [less than 0 °C (30
°F) or more than 30 °C (90 °F)]. For more infor-
mation on storing the battery, see page 8-31.
TIPMake any necessary repairs before storing the
